Your SVN account has been set up.
For anonymous browsing and checkout, use http://svn.mozilla.org
The svn url for locale related checkins/checkouts will be
svn+ssh://svn.mozilla.org/projects/mozilla.com/trunk/{locale}/
Your e-mail address will be your svn login as well. You can pass this user
name directly on the svn url in the command line, but some svn clients get
confused with commands like this. In the example below substitute
'email@host.tld' with your e-mail address.
svn co svn+ssh://email@host.tld@svn.mozilla.org/blah
They interpret 'host.tld' to be the svn repository host name and
svn.mozilla.org to be the revision. In unix environments, to get around this
(client confusion), put this in your ~/.ssh/config
Host svn.mozilla.org
User email@host.tld
Then, you can simply use "svn co svn+ssh://svn.mozilla.org/blah"
Please refer to copious google search results to get this working on non-unix
platforms.
